Class EbuR128LevelBlock

Namespace
VisioForge.Core.MediaBlocks.AudioProcessing
Assembly
VisioForge.Core.dll

EBU R128 loudness level measurement block using ebur128level from rsaudiofx plugin. Measures and reports loudness levels according to EBU R128 standard including momentary, short-term, and integrated loudness measurements, loudness range, and peak levels. Essential for broadcast compliance, audio mastering, and loudness monitoring applications. Implements the VisioForge.Core.MediaBlocks.MediaBlock. Implements the VisioForge.Core.MediaBlocks.IMediaBlockInternals. Implements the IDisposable.

public EbuR128LevelBlock()

Properties

Input

Gets the input.

public override MediaBlockPad Input { get; }

Property Value

MediaBlockPad

Inputs

Gets the inputs.

public override MediaBlockPad[] Inputs { get; }

Property Value

MediaBlockPad[]

Interval

Gets or sets the measurement interval. Determines how often measurement results are calculated and reported. Default: 1 second.

public TimeSpan Interval { get; set; }

Property Value

TimeSpan

Mode

Gets or sets the measurement mode flags. Specifies which types of loudness measurements to calculate. Default: All measurement modes enabled.

public EbuR128Mode Mode { get; set; }

Property Value

EbuR128Mode

Output

Gets the output.

public override MediaBlockPad Output { get; }

Property Value

MediaBlockPad

Outputs

Gets the outputs.

public override MediaBlockPad[] Outputs { get; }

Property Value

Methods

Build()

Constructs and initializes the EBU R128 level measurement filter and its associated GStreamer elements. This method creates the filter with the specified measurement parameters, establishes input and output pads, and prepares the block for measuring loudness levels according to EBU R128 standards.

public override bool Build()

Returns

bool

true if the filter was successfully built and configured; false if initialization failed.

CleanUp()

Releases all resources and performs cleanup operations for this EBU R128 level measurement block. This method disposes of the GStreamer elements and resets the build state.

public void CleanUp()

Dispose(bool)

Releases unmanaged and - optionally - managed resources.

protected override void Dispose(bool disposing)

Parameters

disposing bool

true to release both managed and unmanaged resources; false to release only unmanaged resources.

GetCore()

Gets the core BaseElement wrapper that provides additional functionality around the GStreamer EBU R128 level measurement filter element.

public BaseElement GetCore()

Returns

BaseElement

The BaseElement wrapper instance that encapsulates the GStreamer EBU R128 level measurement filter.

GetElement()

Gets the underlying GStreamer element that performs the loudness level measurement.

public Element GetElement()

Returns

Element

The GStreamer Element instance representing the EBU R128 level measurement filter.

IsAvailable()

Determines whether this media block is available. Correct NuGet SDK redist should be included into your project.

public static bool IsAvailable()

Returns

bool

true if this media block is available; otherwise, false.

IMediaBlockInternals.SetContext(MediaBlocksPipeline)

Associates this EBU R128 level measurement block with a pipeline and initializes its internal context. This method is called internally when the block is added to a pipeline.

void IMediaBlockInternals.SetContext(MediaBlocksPipeline pipeline)

Parameters

pipeline MediaBlocksPipeline

The MediaBlocksPipeline instance that will manage this block.
